Description

Technical Field

[0001] This utility model relates to the field of bearing cage inspection, and in particular to the field of cage hole position inspection technology, specifically a cage hole position inspection tool. Background Technology

[0002] The core function of the existing bearing cage is to separate and guide the rolling elements, ensuring their even distribution between the inner and outer raceways. If the position of the circular holes is off, it will lead to: uneven spacing between the rolling elements, with some rolling elements bearing loads far exceeding the design value, while others are underloaded; concentrated stress will accelerate the wear of the rolling elements and raceways, and may even cause localized plastic deformation and cracks, leading to premature bearing failure in severe cases. An irregularly shaped cage with flanges on both the outer and inner walls has a complex shape. The detection of the holes around the cage is often carried out using coordinate measuring machines, which takes a long time. Therefore, a fast detection fixture needs to be designed.

[0017] This utility model proposes a cage hole position inspection tool for use in the cage hole position inspection process. The base 1, clamping block 3, product positioning group 4, rotating seat 5 and manual rotating group 6 of this utility model are specifically designed for irregular cages with flanges on both the outer and inner side walls. The structure is particularly suitable for quickly inspecting the holes around the cages with flanges on both the outer and inner side walls.

[0018] In general, the cage hole position gauge proposed in this utility model mainly includes: a base 1, a clamping block 3, a product positioning group 4, a rotating seat 5, and a manual rotation group 6. (See also...) Figure 1 It shows the arrangement of base 1, clamping block 3, product positioning group 4, rotating seat 5 and manual rotation group 6.

[0019] The cage hole position gauge proposed in this utility model should be used before... Figure 1 As shown, the cage to be tested is inserted into the top outer side of the hole block 2 in the product positioning group 4. The cage is rotated so that the bottom of the outer flange of the cage is engaged in the flange positioning notch 461 in the flange positioning block 46 of the product. Before testing, the handle 66 in the manual rotation group 6 is rotated counterclockwise so that one side of the insert head 441 in the high-precision insert 44 abuts against the groove of the plum blossom groove 51, and the insert post 442 in the high-precision insert 44 does not contact the notch relief groove 21. When in use, Figure 2As shown, the drive handle 66 drives the rotating seat 5 to rotate clockwise, so that one side of the insert head 441 in the high-precision insert 44 abuts against the protrusion of the plum blossom groove 51. The insert post 442 in the high-precision insert 44 passes through the circular holes around the retainer and enters the semi-circular groove 22. If it abuts against the bottom inner wall of the semi-circular groove 22, the product is qualified. If the insert post 442 gets stuck before touching the bottom of the semi-circular groove 22 during the rotation of the handle 66, and the handle 66 cannot be driven to rotate further, the retainer is unqualified. After the inspection is completed, the drive handle 66 is rotated back to make the insert post 442 leave the holes around the retainer. The retainer is then removed to complete the inspection process. The retainer hole position inspection tool proposed in this utility model can simultaneously inspect the holes on the retainer. If any hole around the retainer has a problem, the inspection will fail. The inspection time is short and the efficiency is high, making it suitable for mass production.

[0020] Based on this, preferably, a detection block mounting hole 11 is opened in the center of the base 1, and a clamping positioning groove 12 is opened on the bottom end of the base 1 on one side of the detection block mounting hole 11. A threaded hole is opened in the center of the bottom of the clamping positioning groove 12. A hole block 2 is installed in the detection block mounting hole 11. A notch relief groove 21 is provided on one side of the hole block 2 corresponding to the clamping positioning groove 12. A clamping block 3 is installed in the clamping positioning groove 12 by bolt connection. One side of the clamping block 3 abuts against and is inserted into the notch relief groove 21. Semi-circular grooves 22 are opened at equal intervals around the top of the hole block 2.

[0021] It should be specifically noted that during the testing process, the protective oil sprayed on the surface of the cage may remain in the notch relief groove 21 of the hole block 2. Combined with the large amount of dust and metal particles in the production center, oil stains are more likely to accumulate in the notch relief groove 21, reducing the overall smoothness and fluidity of the product. When rotating the handle 66, the sticky feeling caused by the dirt may lead the testers to misjudge whether the product is qualified. Therefore, the hole block 2 is designed to be detachable and has a corresponding clamping positioning groove 12 and a corresponding clamping block 3 for positioning. This makes it easy to remove the hole block 2 for ultrasonic cleaning and then reinstall it for use.

[0022] Preferably, the product positioning group 4 is set on the outside of the hole block 2 by bolt connection. The product positioning group 4 includes: annular embedded groove 41, positioning block 42, detection hole 43, high-precision insert 44, spring 45 and product flange positioning block 46. The annular embedding groove 41 is arranged around the outside of the hole block 2. The left and right sides of the annular embedding groove 41 are provided with positioning platform grooves 411. The positioning block 42 is fixed in the annular embedding groove 41 by bolt connection. The left and right or front and rear sides of the positioning block 42 are provided with platform surfaces 421 corresponding to the positioning platform grooves. The platform surfaces 421 are in contact with the platform grooves. It should be specifically noted that the positioning block 42 is designed to be detachable, which is convenient for daily maintenance and cleaning, and is easy to replace when the spring 45 fails. The platform surface 421 and the platform groove are used as positioning, so that after disassembly and reinstallation, there is no need to manually adjust to align the detection hole 43 with the semi-circular groove 22. Detection holes 43 are equally spaced around the positioning block 42. High-precision inserts 44 are inserted into the detection holes 43. One side of the insert head 441 in the high-precision insert 44 abuts against the inner wall of the plum blossom groove 51 in the rotating seat 5. One side of the insert post 442 in the high-precision insert 44 extends through the detection holes 43 toward the notch relief groove 21. It should be specifically noted that this technical solution uses the relatively common high-precision insert 441 as the fixture body, which reduces the production cost of this device. Furthermore, the outer diameter of the high-precision insert 441 can be uniformly processed to meet the minimum tolerance of the cage hole position, enabling the fixture to perform a function of checking whether the hole diameter is greater than the minimum tolerance in the process.

[0023] Spring 45 is fitted on top of high-precision insert 44, with one side of spring 45 abutting against insert 441 and the other side of spring 45 abutting against the outer wall of positioning block 42. It should be specifically noted that the spring 45 can cause the high-precision insert 44 to leave the notch relief groove 21 during the counterclockwise rotation of the handle after the test is completed. The product flange positioning block 46 is bolted to the top of the base 1, located between the inner wall of the positioning block 42 and the outer wall of the hole block 2. The product flange positioning block 46 has a flange positioning notch 461 on the side near the hole block 2. It should be specifically noted that the product flange positioning block 46 serves to position the cage to be tested. During testing, it is not necessary to align the cage hole with the semi-circular groove 22 before testing. Furthermore, the product flange positioning block 46 is made of copper, which has relatively stable properties and will not rust or contaminate the product surface. In addition, copper has low hardness and will not scratch the product surface during the testing process.

[0024] Preferably, the rotating seat 5 is placed on top of the base 1, and the rotating seat 5 is fitted onto the outside of the product positioning assembly 4. A manual rotating assembly 6 is provided around the rotating seat 5. The manual rotating assembly 6 includes: a positioning boss 61, a locking screw hole 62, a cup-head hexagonal screw 63, a bearing 64, a handle mounting hole 65, a mounting screw hole 67, and a handle 66. The positioning boss 61 is located on the outer wall of the rotating seat 5 base. Locking screw holes 62 are opened at the top corners of the base 1, located on the outside of the rotating seat 5. A cup-head hexagonal screw 63 is threaded into the center of the locking screw hole 62. A bearing 64 is fitted onto the top of the cup-head hexagonal screw 63, with one side of the bearing 64 abutting against the outside of the rotating seat 5. The bottom side of the bearing 64 is set on the top step surface of the positioning boss 61. It should be noted that the inner ring of the bearing and... A portion of the bottom of the outer ring is set on the top step surface of the positioning boss 61 for support. The outer side wall of one side of the outer ring of the bearing 64 abuts against the outer side wall of the rotating seat 5, which plays a positioning and limiting role. The top of the inner ring of the bearing 64 is in contact with the screw head of the cup head hexagonal screw 63. After the bearing 64 is installed, it is locked by the cup head hexagonal screw 63. The handle mounting hole 65 is opened on the outer side wall of the rotating seat 5 between two adjacent locking screw holes 62. The handle 66 passes through the handle mounting hole 65. The mounting screw hole 67 is opened at the top of the rotating seat 5. The bottom of the mounting screw hole 67 communicates with the handle mounting hole 65. The locking bolt 68 passes through the mounting screw hole 67. The top screw head of the locking bolt 68 abuts against the top of the rotating seat 5. The bottom stud of the locking bolt 68 passes through the mounting screw hole 67 and abuts against the outer side wall of the handle 66.

[0025] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
